CO2-Cascade systems

You decide, we have the solution.

WITT CO2-Cascade systems are a future-proof, sustainable solutions using the benefits of the refrigerant CO2. In the WITT workshop in Aachen we will build cascade system according to your individual needs and deliver it with all required components, such as refrigerant pumps or plate heat exchangers. For fast and easy installation on site we pre-assemble and align the entire cascade and certify it in one unit.

Of course we look at the relevant conditions of your refrigeration system to match all the components for trouble-free operation.


According to your individual needs you decide as flexible as possible what additional accessories you would like to add to your CO2-Cascade system, such as:

  • Stop valves
  • Overflow valves
  • Service valves
  • Automatic fast acting valves
  • HR and HS high-pressure float regulators
  • NGX maximum level switch
  • Stand pipe with level control
  • Differential pressure piping incl. pressure gauges and
  • WITT oil management
  • filter driers

The positioning of connections on the pressure vessel for inlet and outlets can be chosen according to your needs taking into account the technical feasibility.
